Mich Application May 27, 1936, Serial No. 1,989- 5 Claims. (miss-181")My present invention relates to improvements in conveyers andparticularly, to conveyers employed'inmetal working foundriesforconveying molds, castings and the like. The objects of improvementsare, first, to provide a conveyer of such'structure thatwthe workmencanpass from side to side without climbing over the conveyer; second, toprovide a conveyer inldivided sections; third, to provideaconveyerthatwill be free from foundry floor obstructions; fourth, toprovide a conveyer having its operative mechanismwbelow the foundryfloor; fifth, to provide a conveyer of simple construction; sixth, toprovide a conveyer whereof the operative mechanism will be enclosed;and, seventh, to provide a conveyer that will" have along operative,life.

I attain the named objects and others that will be apparent from aperusal of the description taken in connection with the accompanyingdrawings, in which:

Figure 1 is an elevation in part section, having a foundry flask withits mold therein in the act of being conveyed.

Figure 2 is an end elevation of one of the carrier sections, andsectional View of the assemblage tunnel.

Figure 3 is a plan view illustrating the arrangement of the carriersections.

Figure 4 is a plan view of one of the carrier sections looking downwardfrom line 4--4 of Figure 1.

Figure 5 is an under side view of one of the carrier sections.

Fig. 6 is a top plan view of the draft rigging by which the trucks ofthe truck train are coupled together.

Throughout the drawings similar numerals refer to similar parts, andreferring thereto:

i represents the top or work supporting table supported above thefoundry floor by columns 2 extending upwardly from the carrier truckplate 3, located in tunnel 4 below the level of the foundry floor, thetruck plate having at its under side journal bearings 5 in which arejournaled axles 6 having flanged wheels 1 running on track rails 8supported on tunnel crossbeam 9, having one of its ends anchored intunnel wall I 0 and its other end supported by angle bracket H onupright column l2. Secured to the upper side of cross beam 9 is carriertruck guide rail l3 engaged by guide wheels Mjournaled on truckconnector pins it carried by the pair of connector straps I6, the upperone of which is secured to downwardly extending lugs ll at the underside of truck plate 3. At the ends of the connector straps lfitare yokesI8 engaging the connector pins 1:5. Connected with the yokes H3 at eachendofi the connector straps l6 are draw bars l9 secured to the yokes [8as by nuts 20. At the top of tunnel 4 are floor plates 2| and 22spaced'apart tofform slot 23 and having their opposed edges supported bybracket, 24 anchored into concrete wall 25 and bracket 26 supported'oncolumn [2 and secured thereto by the-angle members 21 and 21a. vWithinthe slot 23 and secured to the extended ends of the brackets 24 and 26are guide members 28 and 29 for guiding and supporting columns 2 havingthe table plate I thereoniniupright position by guide wheels 30journaled onking' pin 3| in the struts 32 of the columns 2 l v Thetunnel 4 is of considerably greater width than the space occupied by theconveyer mechanism to allow room for entrance when cleaning the tunneland lubricating the operative mechanism. Removable floor plates 33 atthe side of floor plates 22 close the opening 33a through which entranceto tunnel 4 is made. At each side of the slot 23 on the floor plates 2|and 22 are upwardly extending flanges 34 which act to stop dirt, sand,gravel and pieces of metal from entering or being swept into the slot.Carried by the columns 2 of the carrier truck is apron 35 having at eachof its sides and outside the upwardly extending flanges 34, downwardlyextending flanges 36. The free ends 31 of the apron 35 of the severalcarrier trucks join to provide a complete continuous covering for theslot 23. 38 represents a foundry flask with mold therein positioned onthe table I in which position the mold is conveyed from the moldingmachine, supported during the pouring of molten metal in the mold andthe shaking out of the casting.

In the employment of my improved conveyer in a casting producingfoundry, the molds are produced on the usually employed moldingmachines, within suitable flasks usually consisting of drag and copemembers. These portions are assembled on the table plate of the conveyerwhich is then moved to bring another carrier truck table in position forthe assembling of another mold. The previously assembled mold, havingbeen moved a sufiicient distance from the assembly station, is pouredwith molten metal and upon being moved still farther from the assemblystation, the poured mold is removed from the conveyer and the casting isremoved from the flask. Movement of the conveyer can be eithercontinuous, as by mechanical power drive, or intermittent, as when movedmanually.

Having described my invention, I claim:

1. In a conveyer comprising a tunnel having a pair of track railssupported above the tunnel floor and having a truck guide railintermediate the track rails, floor plates at the top of the tunnel inspaced relation to provide a slot between their opposed edges withdownwardly extending guide members at the sides of said slot, aplurality of trucks in endless connected relation supported on saidtrack rails and guided thereon by a plurality of guide wheels carried bysaid trucks and engaging the said guide rail, column members extendingupward from the truck through said slot between said floor plates andhaving a guide wheel engaging the said guide members at the sides ofsaid slot and a table carried by said columns above said floor plates,the said columns having intermediate said truck and said table a strutextending between and joining said columns, the said strut supportingintermediate the said columns a guide wheel engaging the said downwardlyextending guide members.

2. In a conveyer, a plurality of trucks in endless connected formation,a plurality of floor plates above the said trucks arranged in twoparallel spaced-apart endless formations having a slot between theopposed sides of the formation, table supporting members extendingupward from said trucks through said slot and carrying an apron formovably covering the slot and a plurality of mold supporting memberscarried by said upwardly extending members in spaced apart formationabove said trucks and said floor plates, and means carried by the saidtable supporting members engaging the sides of said slot for guiding thesaid members and means associated with the said truck for guiding thetruck.

3. In a conveyer, a plurality of trucks in endless connected formation,a plurality of floor plates above the said trucks arranged in twoparallel spaced-apart endless formations having a slot between theopposed sides of the formations, table supporting members extendingupward from said trucks through said slot and carrying an apron formovably covering the slot and a plurality of mold supporting memberscarried by said upwardly extending members in spaced apart formationabove said trucks and said floor plates, and means associated with thesaid truck for guiding the truck.

4. In a conveyer, a plurality of trucks in endless connected formation,a plurality of floor plates above the said trucks arranged in twoparallel spaced-apart endless formations having a slot between theopposed sides of the formations, table supporting members extendingupward from said trucks through said slot and carrying an apron formovably covering the slot and a plurality of mold supporting memberscarried by said upwardly extending members in spaced apart formationabove said trucks and said floor plates.

5. In a conveyer consisting of a plurality of truck members in connectedformation within a tunnel and a flask supporting table carried bycolumns extending upward through a slot in the top of the tunnel tosupport the said table, a cover for said slot associated with the saidcolumns and carried by said truck members.
